Application March 24,

5, Claims.

This invention relates to polishing and brushing machines, as described in my copending application, Serial No. 670,733, filed May 12th, 1933, and has for its main object to provide a machine wherein both the polishing and brushing means will be carried simultaneously, said machine being adapted to be used either as a polishing or brushing machine without any exchange of the parts.

Still a further object of my invention is to provide a machine, as characterized hereinbefore,

' which will have means incorporated therein whereby one set of operative devices, like those used for polishing operations may be put into active position while another set of operating devices, like those used for brushing operations will be made inactive, or vice versa, so that the machine may be used alternatingly for brushing or polishing operations, as desired. It will be obvious that based on the same principle a machine may be built which will beadapted for more than two alternating operations in case the same'may be desired to be used for some other kind of relating operation aside of brushing or polishing.

Qther objects of this invention will be apparent as the specification of the same proceeds.

In the drawings forming a part of this speciflcation and accompanying the same:

Fig. 1 is a plan view of my assembled machine, a part of the same being broken away and shown in section;

Fig. 2 is a sectional elevation of my assembled improved machine, the section being taken on the line 2-2 of Fig. 1;

Fig. 3 is a bottom view of my novel machine, while Fig. 4 shows a circular cylindrical section of my device, generally on the lines 4-4 of Fig. 2, said cylindrical section being shown in an imaginary developed or flattened condition in a fragmentary manner;

Figs. 5 and 6 are a plan view and a side elevation, respectively, of a slidable brush used in my device. Referring now to the drawings more closely, by

characters of reference, my invention is provided with a housing l0 having an upper compartment II and a lower compartment l2 and a partition wall l3 between said two compartments, said housing being generally of a cylindrical shape and placed in a vertical position when used in' my invention. In the upper compartment ll of the housing, a rotor or turbine 14, having a plurality of vanes I5, is arranged on a rotating disc Ma and terminated by outer and inner imaginary cylinder surfaces I6 and I1, respectively, as is well known Cal 1934, Serial No. 717,243v

the rotor H by which the same is secured on avertical shaft IS. A removable cover 2| may be provided for the housing l0 and in the center thereof may be arranged a ball-bearing, generally indicated by the numeral 22 for the upper end of the shaft I 9. t Y

A second ball-bearing 23 may be provided on the partition l3, shaft I9 projecting through said second ball-bearing 23 and the lower end 24 of said shaft may carry in a removable and exchangeable manner the operating device proper 25 secured thereon. Said operating device 'is shown in this embodiment of my invention as a rotating frame 26 slidably secured to the lower end 24 of the shaft l9, as shown in Fig. 2 but not described in this specification more in detail, since'it will be understood by those versed in this art and since it is is not needed to be detailed for the purposes of this application. Said frame 26 is pressed downwardly towards the floor 21 by the spring 28 as will be understood and as has been more fully explained in my copending application mentioned hereinbefore. The operating devices proper of my machine are arranged in said frame 26, as will be more fully explained hereinafter.

The upper compartment ll of the housing I0 is continued in an air conduit 32 through which compressed air or other gas may be introduced, as indicated by the arrow 33, from any suitable source, with a pressure andvelocity as desired. For a convenient and easy use of my invention said conduit 32 may be provided with means whereby it may be attached to an outlet opening on the usual vacuum cleaner and my device operated therethrough.

The air will follow the internal contour of the air conduit 32 (Fig. 1) and will strike the vanes 15, as at 34, will then pass through them in a certain case, that is, at a certain speed, pressure and other factors of operation, following the direction generally indicated by the dot and dash line 35 and leaving the inner openings of the vanes at 3511 will pass through the space in the rotor following the line 36 and will exit following the center line 31 striking the vanes once more at 2 in the wall of the compartment H (Fig. 2) substantially opposite to the conduit 32 and being spread at that portion of said wall to a certain distance, as has been shown more in detail in my copending application.

.The wall of the lower compartment l2 of the housing In extends outwardly, as at 44, and is continued in an outer second downwardly projecting wall 45, the lower portion 46 of the wall of the compartment i2, the outwardly projecting extension 44 thereof, and the outer wall 45 forming a circular downwardly open channel 41. A lining member 48 is secured in said channel 41, said lining member in this embodiment being shown as made of wood but, of course, it may be made of any other suitable material, like a metal stamping or casting. A plurality of slidable downwardly turned bristle or felt brushes, generally of the construction indicated in Figs. 5 and 6, are arranged in said lining piece 48, for the purpose of supporting my machine on the floor 21, by resting on said brushes, as has been explained more in detail in my copending application mentioned hereinbefore. Each of said resting brushes has an upper frame member 49, generally of an oval contour and following the curvature of the center circle of the channel-41, the active brush or felt part 50 being secured into said upper frame 49, which is shown in this embodiment as made of wood but which, of course, may be of any other material and any other suitable construction, as will be understood by those versed in this art.

In the embodiment of my device shown in the drawings I employ three bristle brushes for resting my device thereon, said bristle brushes being indicated by the numerals 5|, (Figs. 2, 3 and 4) and I also employ three felt resting devices indicated by the numerals 52, all of these resting devices being slidable upwardly and downwardly in appropriate openings in the lining piece 48. Each brush or felt device also has an upstanding central wedge 53 secured thereon in the design shown in Figs. 5 and. 6 and a complete circular slot 54 is provided in the upper central portion of the lining piece 48 in which said wedges 53 may be guided in an upwardly and downwardly sliding manner.

A circular depression 55 is also provided in the top part of the lining piece 48 in which depression is arranged a circular ring 56 slidable therein in a circular manner.

The bristle and the felt brush devices 5i and 52 are arranged alternatingly and preferably in pairs opposite one another, as shown in Figs. 3 and 4, their wedges 53 being oppositely turned towards one another, and a similar but downhanging wedge 51 is secured on the rockably slidable ring 56 between each pair of bristle and felt devices 5| and 52, said downhanging wedge 51 being double acting to co-operate with either of the wedges 53 at the two sides thereof upon a right hand or left hand rocking of the ring 56, as will be obvious, and said downhanging wedges 51 are also adapted to play in said center slot 54 of the lining piece 48. In the rear of the machine the ring 56 will have a boss 58 to which is secured a handle device 59 operating in a slot 60 so that when the handle 59 is moved in a right handed or left handed direction through the slot 60 the ring 56 will describe the same movement and will cause the double acting wedges 51 to engage either all the wedges on the bristle devices or all the wedges on the felt devices and in the first case all the bristle devices will be pushed downwardly, while all the felt devices will be permitted to ride upwardly, as shown in Fig. 4, while in the second case the play of the bristle and the brush devices will be the reverse. All the bristle and brush devices are normally pressed upwardly by the springs 61 playing in holes 62 and pressing against a separate bottom plate 63 secured to the lining piece 46. a

In the operation of such machines it is sometimes desired to use them as brushes while at other times we want to use them as polishing machines. In case the machines are to be used as brushes, ring 56 will be turned in such a manner that the brush devices 5| will engage the floor 21 while the felt devices 52 will be drawn up into an inactive position, while in case the machine is to be used for polishing operations, ring 56 will be moved in an opposite direction, the felt devices will be made active and the bristle or brush devices proper will be permitted to be pressed upwardly in the machine into an inactive position by the spring 6|, as will be obvious. Thus, I provide a machine which, without any exchange of parts and with a very simple regulation movement or operation of some of its parts, may be used either for brushing or for polishing operations.

The actual brushing or polishing operation will be done by the central rotating operating part 25 of my device, as will be obvious, which may also have a plurality of bristle brushes proper 64 and felt devices 65 arranged in the frame 26.

It will be understood that changes and variations may be made in the parts and combinations of my device and I hereby reserve all my rights to any and all such changes as are within the spirit of the invention and the scope of the appended claims.
